Subject: [PATCH] net: mvneta: use cache_line_size() to get cacheline size
Date: Fri, 1 Apr 2016 17:12:49 +0800 [thread overview]
Message-ID: <1459501969-7083-1-git-send-email-jszhang@marvell.com> (raw)
L1_CACHE_BYTES may not be the real cacheline size, use cache_line_size
to determine the cacheline size in runtime.
